plugin v3: How to install custom cores?

[edogaldo]

I'd like to add the stm32duino core (https://github.com/rogerclarkmelbourne/Arduino_STM32) for STM32 MCUs. This core at the moment has not a json file.
I tried to put the core in the "private hardware path", this way the plugin can somewhat see it but variable {runtime.tools.arm-none-eabi-gcc.path} in platform.txt seems not set leading to errors:

• "Program "\bin\arm-none-eabi-g++" not found in PATH"
• "Program "\bin\arm-none-eabi-gcc" not found in PATH"

Notes:

• in standard Arduino installations the stm32duino core uses the toolchain of the Arduino Due core (just need to install the Arduino Due core to be able to successfully compile with stm32duino)
• I installed the Arduino Due core which drove the installation of the arm-none-eabi-gcc toolchain
• in the Arduino Due core variable {runtime.tools.arm-none-eabi-gcc.path} is correctly set
• I can successfull compile using the Arduino Due core

Where/when/how variable {runtime.tools.arm-none-eabi-gcc.path} is set?

I think this is a duplicate. Can you upgrade to the nghtly?
Use the update process. Do not use the download nightly product as that will install V4 which is still pretty unstable.

Thanks @jantje, yes, the problem seems similar.
How to upgrade to the nightly?

[edogaldo]

Plugin version currently installed is 3.1.0.201608012005
If I do

Help > Installation Details > select "Arduino Eclipse Extensions" > click Update

I get message "No updates were found in available software sites"

This version seems NOT fix the problem.

Ok, found the way to install the latest nightly build: 3.1.0.201609060208

I can confirm this fixes the problem!

Thank you very much and best regards, E.

That is because you do not have http://eclipse.baeyens.it/nightly active in your update sites.
